The invention provides a pressurization-decompression enhanced SBR (sequencing batch reactor activated sludge) residual sludge reduction method, and belongs to the technical field of sewage treatment.The method comprises the following steps: 1) SBR residual sludge is subjected to sludge floc breakage, and a broken sludge mixed solution is obtained; 2) the broken sludge mixed solution is subjectedto multi-stage pressurization-decompression enhanced sludge reduction, and a reduced mixed solution is obtained; 3) the reduced mixed solution is subjected to phosphorus recovery, solid-liquid separation is performed after phosphorus is recovered, and a supernatant obtained after separation is returned to SBR to complete sludge reduction, wherein ozone is added to the broken sludge mixed solutionin the multi-stage pressurization-decompression enhanced sludge reduction process, the dosage of ozone is 0.01-0.1 gO3 / gTSS. With adoption of the method, the sludge reduction effect can be improved,total phosphorus and total nitrogen are removed, and the sewage treatment efficiency in the reduction process is improved.

The application belongs to the medical field, and proposes an irreversible acoustic perforation device, a device and a computer-readable storage medium. The device includes an ultrasonic intervention module, an ultrasonic electronic excitation module, an ultrasonic imaging monitoring module and a control module, and generates ultrasonic waves through the ultrasonic electronic excitation module. The ultrasonic intervention module emits ultrasonic waves that can be focused on the region of interest, thereby generating cavitation bubble clouds in the region of interest of the target tissue, and using the cavitation effect to form multiple irreversible pores in the outer membrane of biological cells, Disrupting the balance of water inside and outside the cell, resulting in apoptosis, to achieve the purpose of ablating biological tissue, it can avoid the thermal deposition problem caused by the use of thermal effects, and it has little damage to the surrounding area, and can preserve the integrity of the cell matrix and other structures around the cell, reducing Pain caused by electroporation treatment, avoid complications caused by high-voltage electrical pulses, and accurately control the ablation through the monitoring imaging module and the control module.

The invention discloses a fresh air unit with purifying, sterilizing and disinfecting functions and its purifying, sterilizing and disinfecting process, which comprises an inlet chamber, a gas purification chamber, a gas heating and disinfection chamber, a gas mixing chamber, a fan chamber, and an air outlet chamber from bottom to top.

The fresh air unit with purification and disinfection functions of the present invention can effectively remove harmful gases such as particulate matter and VOC in the air, kill microorganisms such as bacteria and viruses in the air, purify and disinfect the air, and can also be used for heating in winter.

The invention discloses a radiofrequency ablation device for spinal neoplasms operation. The radiofrequency ablation device comprises a radiofrequency electrode for ablating the neoplasms and a conveying component for conveying the radiofrequency electrode to the position of the neoplasms. The conveying component is provided with a bendable part and a telescopic part. The device further comprises a bending control assembly for controlling the bendable part to be bent and a telescopic control assembly for controlling the telescopic component to stretch out or draw back. The bending control assembly and the telescopic control component can convert rotating movement into linear movement so as to control the bendable part to be bent and the telescopic control assembly to stretch out and draw back. The radiofrequency ablation device for the spinal neoplasms operation can position the radiofrequency electrode to the portion where the neoplasms is located precisely, and the neoplasms of different sizes and in different shapes can be ablated.
